Hi Jerry,

I've been asked to help you with your hamster. Of course it's impossible to be certain based only on an online description, it sounds like your hamster may have an abscess. Abscesses often result after a small wound. Lumps that feel hard are more likely to be tumors. Even benign tumors often grow so large that they interfere with movement. All lumps do require treatment by a vet. Abscesses need to be lanced, and then systemic antibiotics are prescribed. don't try to lance the lump on your own. If it is an abscess, you're likely only to push the infection deeper into the body. If it's not an abscess, you'll create a nasty wound. This isn't an emergency, but I would make an appointment early this coming week. These links will take you to directories of vets who treat rats, and would also be good with hamsters:

I recommend that you get rid of the cedar litter. I'm not sure why pet stores continue to sell it. It has been linked to skin problems, respiratory disorders, and liver disease. The best litter is CareFresh, in the colorless and unscented variety. If you have more questions, just let me know by clicking on REPLY. I hope your hamster will quickly reach a full recovery.
